[tex-live] texlive 2018 doesn't work on redhat/centos 6

[Greg' Ar Tourter]

Hi,

What is the minimum system requirement for the binaries in texlive 2018?
The reason I ask is because I have just installed pretest on one of our
server running centos6 and binaries seems to require glibc 2.14 (RH/centos
6 comes with 2.12):

running mktexlsr ...
done running mktexlsr.
running mtxrun --generate ...

tlmgr: mtxrun --generate failed (status 1), output:
texlua: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by
texlua)

kpsewhich: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by
kpsewhich)
kpsewhich: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by

kpsewhich: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by
kpsewhich)
Cannot open /web2c/updmap.cfg for writing: No such file or directory at
/opt/bridge/texlive/2018/tlpkg/TeXLive/TLUtils.pm line 2894.

Is that intentional?

Cheers

Greg
