Hi Josh,

Josh Marshall <Josh.Marshall@jax.org> skribis:

> `guix pack --format=squashfs bash-minimal ...` fails on CentOS7 with SELinux disabled.

The error message normally says something like:

  View build log at /var/log/guix/drvs/…

Could you post that file?

Also, what is the output of “uname -sr” on this machine?

Thanks in advance!

Ludo’.

The log you posted reads this:

--8<---------------cut here---------------start------------->8---
Creating 4.0 filesystem on /gnu/store/mhhlqyazyvwz72y6dwh56fs1zlrvrl0h-squashfs-pack.gz.squashfs, block size 131072.

[...]

Number of uids 2
	unknown (0)
	nixbld (987)
Number of gids 2
	unknown (0)
	nixbld (980)
Failed to read existing filesystem - will not overwrite - ABORTING!
--8<---------------cut here---------------end--------------->8---

I was able to reproduce it on a CentOS 7 system and to strace the
‘mksquashfs’ process, and found that this had to do with access to
SELinux extended attributes.

Fixed in commit 53c594cb3f1f783fea18be6da23a863b00c14f5f.

Thanks!
