Gentoo detected as OracleLinux

[stefson]

when I fire up /usr/bin/cargo -vV on gentoo, it shows the following:

/usr/bin/cargo -Vv
cargo 1.58.0
release: 1.58.0
host: x86_64-gentoo-linux-musl
libgit2: 1.3.0 (sys:0.13.23 vendored)
libcurl: 7.79.1 (sys:0.4.51+curl-7.80.0 system ssl:OpenSSL/1.1.1n)
os: OracleLinux [64-bit]

this missdetection happens, as your crate does depend on lsb-release to be installed at runtime to check for a version. Unlinke debian, gentoo doesn't have "real" fixed version numbers since it is a rolling release distro. Therefore, installing lsb-release repeating the command shows:

/usr/bin/cargo -Vv
cargo 1.58.0
release: 1.58.0
host: x86_64-unknown-linux-gnu
libgit2: 1.3.0 (sys:0.13.23 vendored)
libcurl: 7.79.1 (sys:0.4.51+curl-7.80.0 system ssl:OpenSSL/1.1.1n)
os: Linux 2.7 [64-bit]

which is a slight improvement, but still not really correct.

A common practice is to use the version of sys-apps/baselayout as the version number of Gentoo. It ships a simple release file:

cat /etc/gentoo-release
Gentoo Base System release 2.7

maybe its possible to exploit that file in the future?

Thanks for the report! I will try to look into it.

ok so in reality this is kind of fixed

current git without lsb-release at runtime:

cargo -Vv 

cargo 1.65.0-dev (ce40690a5 2022-08-09)
release: 1.65.0-dev
