Package: util-vserver
Severity: normal
Version: 0.30.216~r2772-3
I'm using a vserver kernel. I get failures within a vserver guest
when i try to test the POSIX-style shared-memory commands with the .c
examples found here:
http://www.cs.cf.ac.uk/Dave/C/node27.html#SECTION002730000000000000000
This turns out to be because the initial creation of /dev/shm inside
the vserver (by initscripts.postinst during a stock lenny debootstrap)
is defeated by
/usr/lib/util-vserver/distributions/lenny/debootstrap.script:
I created a stock debian vserver with:
vserver monkey build -m debootstrap --context 101 --hostname monkey -- -d
lenny -m http://ftp.us.debian.org/debian
All this basically does is set up some vserver configs and then invoke
debootstrap like this:
vnamespace --new /usr/sbin/debootstrap lenny
/etc/vservers/.defaults/vdirbase/monkey http://ftp.us.debian.org/debian
/usr/lib/util-vserver/distributions/lenny/debootstrap.script
After the debootstrap completes,
.../distributions/lenny/debootstrap.script monkeys around with /dev
within the chroot to replace it with the raw initial /dev:
[...]
function fixupDebian
{
$_RM -rf "$1"/dev
$_MV "$1"/dev.X "$1"/dev
}
[...]
mv "$VDIR"/dev "$VDIR"/dev.X
"$_VNAMESPACE" --new -- \
"$DEBOOTSTRAP" $options "$@" "$DISTRIBUTION" "$VDIR" "$MIRROR" "$script" ||
: ## HACK: ignore all errors...
fixupDebian "$VDIR"
[...]
However, one of the jobs of the initscripts.postinst (which is run
during debootstrap) is to create /dev/shm for systems that do not have
a dynamically-populated /dev.
If the following two steps are done from the host before starting the
vserver, POSIX-style shared memory seems to work within the vserver
for me:
mkdir /var/lib/vservers/$VSERVER_NAME/dev/shm
chmod --reference=/dev/shm /var/lib/vservers/$VSERVER_NAME/dev/shm
Perhaps this directory should be added into the default deboostrap
operation?
Are there other ways to resolve this that i missed?
