But is btrfs available today and actively supported on z/Linux? Which has greater function? Greater stability? More congenial licensing terms? Can z/Linux boot from btrfs? If not, what filesystem types are supported for boot?
(Concerning the chatter about availability of PDSE at NIP: For a while, I was running an OpenSolaris guest on x86. Its only filesystem was a ZFS, although I suspect it had an elaborate boot record extension. But this demonstrates that it is possible to start up with a sophisticated filesystem/DSORG/DSNTYPE.) -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
