mkosi: Allow setting version-tag option via VERSION_TAG env variable

With https://github.com/systemd/mkosi/pull/630, we can set environment variables for the build script in mkosi. Let's modify the build script so we can set the version-tag option via an environment variable of the same name. The default is the empty string which causes meson to fall back to the default behavior (git version).

Zbigniew Jędrzejewski-Szmek	3bc66bfa01	rpm: expose $systemd_util_dir also as rpm macro This variable (a.k.a. rootlibexecdir), was exposed through the .pc file, but not as rpm macro. The .pc file must be located in the package that provides libraries, which pulls in a lot of dependencies. In Fedora, the macros are split out to a separate package so that other packages which need to refer to some systemd path but don't otherwise require it, can only pull in the (much smaller and dependency-less) macros package. zram-generator uses the path to specify the location of systemd-makefs, so by using the rpm macro we'll be able to use a much smaller buildroot.	2021-01-15 19:54:43 +00:00

Lennart Poettering	41979f59d3	fs-util: make laccess() macro follow our usual error propagation Functions defined by us are supposed to return negative errno-style errors on errors. laccess() is for access() what lstat() is for stat(), but defined by us as a macro. This led to some confusion regarding error handling. Let's return a negative errno code just in case. This means callers can it use either way: like access(), i.e. checking for a negative return value + looking at errno, or like our own code, i.e. using the negative errno code it returns.	2021-01-15 19:14:10 +00:00
Daan De Meyer	064b8e2c99	meson: Use configure_file when version-tag is specified vcs_tag() is slow. When the version-tag meson option is set, we can use configure_file() directly to speed up incremental builds. Before (with version-tag set to v247): ``` ‣ Running build script...
