Comment # 20 on bug 1184392 from Stefan Hundhammer

A "zypper dup" just now brought me some new virtualbox* packages (among a lot
of others), but that didn't seem to change anything (after rebooting the VM, of
course):

[sh @ balrog-tw-dev] ~ 2 % mount | grep work
work_src on /work/src type vboxsf (rw,nodev,relatime)
work_tmp on /work/tmp type vboxsf (rw,nodev,relatime)

[sh @ balrog-tw-dev] ~ 3 % sudo umount /work/src

[sh @ balrog-tw-dev] ~ 4 % sudo mount -t vboxsf -o uid=1000,gid=100 work_src
/work/src

[sh @ balrog-tw-dev] ~ 5 % ls -l /work/src
total 32
