[gentoo-user] startup script use the wrong find command

[gentoo-user] startup script use the wrong find command

[Xi Shen]

hi,


when i boot my system, at the step "Wiping /tmp", it pops up an error
message saying that the find command do not support the '-uid' option.
in the error message, i also see the busybox mark. it looks like it
used the wrong find command.

i build the kernel my self, and have a initramfs file.

Did you emerge busybox with the make-symlinks USE flag? When your original 
find is replaced by a link to busybox.
Don't know what to do exactly, most probably many other commands will also 
not work as expected, I guess you need to re-emerge all stuff that 
provides them, like findutils. There was a thread recently, look for "/bin 
contains busybox executables after installing busybox-1.13.2" by Amit Dor-
Shifer on 2009-11-25.

Good luck,

I'm almost sure your problem is identical to that of this thread

Re: [gentoo-user] startup script use the wrong find command

[Xi Shen]

well, my find is still at /usr/bin/find, and after the system has
boot, i can use find command normally.

i think my problem is caused by the init script in the initramfs file.
in that script, i install busybox with busybox --install -s. but i do
not know how to uninstall it, or how to fix my problem.

That's unlikely. His box will likely not boot if he did that. If it does boot 
it certainly will not emerge anything. Portage relies on features that are 
present in GNU utilities and are not there in busybox

He likely installed busybox into the initramfs instead of GNU utilities.

initramfs on gentoo is not a technique I recommend. It is designed for a 
general use-case not present in Gentoo[1], and a very few specific cases where 
an initramfs-less setup cannot work[2[

[1] Binary distros cannot know upfront what the end-user has hardware-wise, so 
cannot build drivers for everything imaginable into the kernel. An initramfs 
is an elegant solution, but one which is overkill for Gentoo (the initial 
statement is usually false)

[2] Some specific boot scenarios require an initramfs even on Gentoo - booting 
off raided volumes where drivers are needed at boot time, encrypted / volumes, 
/ on an LVM volume and a few others

In almost all other cases it is simpler and easier to dispense with the 
initramfs and build two drivers into the kernel. After all, the user in all 
probability knows exactly what hardware they have

yes, i installed busybox into the initramfs i created my self. because
i see the initramfs generated by genkernel uses it.

i am using LVM, so i have to use a initramfs. are you suggesting that
i should install all the GNU utilities into the initramfs? i think
that would create a very large initramfs file.

Do you mean / on LVM?

Personally, I don't trust busybox on full scale installs, or on anything 
that's not embedded. Busybox necessarily omits certain features to keep the 
size and simplicity down whereas boot utilities are too often written for GNU 
tools.

[Xi Shen]

yes i use / on LVM.

i just cannot understand why the busybox in the initramfs that
genkernel generates works fine, while mine reports error.

Me too.

And I do not understand why the "wiping tmp" stuff actually happens while 
you are still in the initramfs. For me, /tmp is not even mounted while 
being in initramfs. My /tmp is also wiped during bootup, but at that point 
the initramfs is already gone and the real system (with a real find 
command) has taken over.

Re: [gentoo-user] startup script use the wrong find command

[Xi Shen]

yeah, that's the point.

the initramfs has already passed, and it seems the system did not
successfully switch_root, and it still using busybox. my init script
in the initramfs is a slightly modified version of the one on this
page http://en.gentoo-wiki.com/wiki/Initramfs
