[gentoo-user] [OT] Customised System Rescue CD -> USB stick and UEFI

[Peter Humphrey]

Hello list,

Has anyone managed to install a customised (or even standard) SysRescCd 
image onto a USB stick so that it will boot in UEFI mode? I wanted to use 
the following partition layout:

(parted) print                                                            
Model: SanDisk Ultra Fit (scsi)
Disk /dev/sda: 59232MiB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags: 

Number  Start     End       Size      File system     Name       Flags
 1      1.00MiB   128MiB    127MiB                    BOOTLDR    bios_grub
 2      128MiB    2048MiB   1920MiB   fat32           boot       boot, esp
 3      2048MiB   4096MiB   2048MiB   linux-swap(v1)  SWAP
 4      4096MiB   16384MiB  12288MiB  ext2            sysrescue
 5      16384MiB  24576MiB  8192MiB   ext2            home

I followed the procedures at https://www.system-rescue-cd.org and thought I 
was getting on all right until it came to re-creating the squashfs with
	/usr/sbin/sysresccd-custom squashfs
Then I got huge numbers of input-output read errors. So I tried it with 
2>/dev/null; it got up to 10% completion and a couple of hundred megabytes 
in sysrccd.dat, then sat in a loop for ever whirling its little spinner.

I thought I'd ask here before trying the forum because of the density of 
experts here.  ;-)

Omitting the customisation and just copying all the files into place on 
/dev/sda4 (root, ext4 with no journal) and /dev/sda2 (boot, vfat) but 
although the "BIOS" saw it was there, when I tried to run it I was dumped to 
a grub shell. I don't know grub well so I couldn't proceed.

If anyone can point me in the right direction I'll be grateful. Ta.

I've done it several times with a stock SysResCd. Just loop mount the ISO
and run the install script.

I've never bothered to try to customise it as I usually only use them to
install Gentoo.

If you think that there is good in everybody, you haven't met everybody.

Yes, I can do that with no trouble; I just wanted to see if I could use 
their instructions to make my own version.

A few times this box has somehow lost its UEFI stubs and I've had to use a 
rescue CD to reinstall them.

I tried this several times. Finally installed Gentoo with Xfce DE and 
all utilities I could think of ever using on a USB drive.
