However, in technical aspects, from filesystems to things as basic as synchronisation (Linux still uses anachronic spinlocks), Solaris is years ahead. Thus my question.
Exactly the opposite... on our aging SPARC IPX machines at the time Solaris barely crawled, Red Hat ran just fine, and gave that iron a few extra years of useful life (Solaris wasn't updated on them anymore). Linux was fast and lean, Solaris was bloat at its worst.
BTW, what is "anachronic" about spinlocks? They do work, and have low overhead. Sure, it looks like the in-kernel synchronization primitives for Solaris are less (and simpler to use); but if the cost is that the system runs much slower, no thanks.
Filesystems? Like the in-kernel MS-DOS filessytem they had, that was so incredibly awfully slow (I seem to remember minutes copying a few smallish files) that the very first thing we did on any Sun machine here was to install mtools to get bearable floppies? Like all the filesystems Linux handles today (I believe almost all important disk partitioning schemes are supported, as are most filesystems, even very obscure ones), and which Solaris doesn't understand at all?
