I checked the permissions for  iscan-data  & they seem ok.
No, I've never tried to use Selinux.

However, I've just escaped fr another beast, ie Linux Mint 19 :
DON'T try to install it alongside Gentoo !!

This beast leads you along to a point where you've told it where to install
-- a partition on my HDD (sdb5) -- ,
you click 'proceed' & it chugs along nicely for some time,
then it says it's trying to install a bootloader
without asking whether you want it to or where to do it.
Next, it says it's failed to install Grub -- which I've never used -- ,
offers several ugly-looking options & freezes.

All you can do is a hard power-off & when you restart,
instead of the regular Lilo box of options, there's only a Grub prompt.
Disaster looks you in the face !

SystemRescue to the rescue : Gentoo  /boot  is unaltered,
so copy  lilo.conf  into the SR  /etc  dir, edit it to use SR paths,
mount the Gentoo  /boot , run 'lilo' & the MBR is restored to what it sb.
Reboot & the familiar Lilo screen appears !

I wanted to see whether the latest Mint found my scanner,
which would suggest that the problem doesn't involve the kernel, at least.
I'm not trying again !

On inspection, Mint 19 does seem to have installed itself on  /dev/sdb5 ,
so I can copy the vital files from its  /boot  to my own Gentoo  /boot ,
edit  lilo.conf  accordingly & see if it will start : not today !

Next up -- too late for today -- is to see if I can get Nvidia working
with an earlier kernel : at present it isn't.
Then I can find out if Xsane can find my scanner with another kernel.

Can anyone take a look at my Strace output ( 3  files),
which is at  http://chass.utoronto.ca/~purslow/test ?
That would be a real help.
