# We need a handwave to make ubuntu happy in order to run bwrap

# see https://etbe.coker.com.au/2024/04/24/ubuntu-24-04-bubblewrap/
|

|
# But, in some cases, it seems that 'ubuntu-latest' does not always
|
|
# 'resolve' to 24.04, so we do some hand waves to check for
|
|
# os version >= 24.04 (otherwise the build can die when
|
|
# trying to apply bwrap.apparmor)

|
|
# operating system identification data.

# The format of os-release is a newline-separated list of
|
|
# environment-like shell-compatible variable assignments.
|

# The file /etc/os-release takes precedence over /usr/lib/os-release.
|

# Applications should check for the former,
|
|
# and exclusively use its data if it exists,
|
|
# and only fall back to /usr/lib/os-release if it is missing.

# excluding any OS name information or release code name,
