[Vmdebootstrap-devel] Bug#822180: Please reset umask before creating files

[Christian Kastner]

Package: vmdebootstrap
Version: 1.5-1
Severity: normal

The umask of the invoking user currently affects how files within the VM
are created. Side effects may include various services failing to start,
eg networking:

> [FAILED] Failed to start Network Service.
> See 'systemctl status systemd-networkd.service' for details.

The log says:
> adt-sid-amd64 systemd-networkd[283]: Could not load configuration files: Permission denied

Use a simple "ls -l $1/etc/network/interfaces.d/*" as a --customize
script, I see
> -rw-r----- 1 root root 63 Apr 21 22:36 /tmp/tmp9c3rY1/etc/network/interfaces.d/setup

The above is the result of a umask of 0027.

Setting umask to 0022 before invoking vmdebootstrap resolves the issue,
however this is a factor that should probably be sanitized by vmdebootstrap.

Regards,
Christian
