[pve-devel] [PATCH container] check sh instead of file for templates architecture type

[Thomas Lamprecht]

/usr/bin/file may not be available, while that has no high
probability we already had bug reports regarding this.

To ensure better compatibility use /bin/sh which every Linux
has (POSIX 1003.1-2004).
