Yes it is. (Thanks for making me feel >40 years younger! :-) If you are under the impression the merged /usr concept was invented by Redhat, or the freedesktop and/or the systemd people, you are demonstrably wrong. On System V Release 4 and later /bin has already been a symlink to /usr/bin, and Solaris implemented the /usr merge about a decade ago. Effectively, only some Unices and some Linux based distributions are the odd ones out in that respect. > > We have a half a decade's history of seeing systemd stick its nose in > the tent, and then keep pushing until the DIY human must leave the > tent.

In my reply to your other post I explain why the notion of a merged /usr allegedly forcing the use of an iniramfs is a myth, I won't repeat it here for the sake of brevity. The part about "acquire, monopolize and decompatablize the tools to create initramfs" is ridiculous, as an initrd is nothing more than an (optionally compressed) cpio archive, loaded by the Linux kernel itself. Put some statically linked executable (e.g. a shell) inside, renamed to /sbin/init, and you have the most bare-bone of Linux systems imaginable, without even the need for a "real" root file system. (Where I used to work we regularly built entire embedded Linux systems that consisted of nothing more than a boot loader, a kernel and an initrd - go figure.) Sorry, but no matter how educated, in this case your guess simply failed. Regards, Urban -- Sapere aude!
