i mean if i build thing with glibc 2.28 installed, and my system has
2.27, then glibc upgrade is needed as well due versioned glibc symbols

This operation will use 7.0MB of disk space.
if open-vm-tools was built with older glibc present on builder, i could
just install the package, not pull glibc and related deps
and this can recurse big enough if some upgraded dependent package pulls
another library rebuild, etc. on some other system i was forced to
install 900mb packages due gdbm, ffmpeg, etc libraries which all
stareted from simple GLIBC_2.28 dep.
