Lintian tag: possible-bashism-in-maintainer-script

Type: warning

Description (from lintian-explain-tags)

This script is marked as running under /bin/sh, but it seems to use a
feature found in bash but not in the SUSv3 or POSIX shell specification.

Some examples are:

- == in a test, it should use = instead - read without a variable in the
argument - function to define a function - source instead of . - . command
args, passing arguments to commands via source is not supported -
{foo,bar} instead of foo bar - [[ test ]] instead of [ test ] (requires a
Korn shell) - type instead of which or command -v

Please refer to Scripts (Section 10.4) in the Debian Policy Manual for
details.

Visibility: warning
Show-Always: no
Check: shell/non-posix/bash-centric
