Subject: bug#30667: 'guix system vm' must keep mount_tag-length limited below 32 bytes for --expose and --share
Date: Thu, 1 Mar 2018 19:05:50 +0100 [thread overview]
Message-ID: <20180301190550.4e403961@alma-ubu> (raw)

I prepared a QEMU VM with:
./pre-inst-env guix system vm \
--expose=/home/bjoern/digikam-testpool/=/image-pool \
../guix-systems/digikam-test.scm
Starting the VM it complained:
$> /gnu/store/zg5a42vcz4qf6h3yrdrijyaxkbhr967s-run-vm.sh
qemu-system-x86_64: -virtfs local,path=/home/bjoern/digikam-testpool/,security_model=none,mount_tag=TAG_home_bjoern_digikam-testpool_: mount tag 'TAG_home_bjoern_digikam-testpool_' (33 bytes) is longer than maximum (31 bytes)
I haven't looked into the Guix code, but I suppose there is somewhere
a place where the command line and the '/etc/fstab' file is filled
with the mount tags.
Here we should check the tag-length and shrink it (uniquely) if
it is more than 31 bytes in size.
