Thanks. You just added concrete to what had to date been a rather hand- wavy discussion, and it's quite useful. =3D:^) Meanwhile, also note that there's PARTLABEL, PARTUUID and ID, that the=20 mount manpage promises to honor. I've not used these myself, but there=20 was a thread on the btrfs list discussing GPT format and users of its=20 partition-labels (as opposed to filesystem labels), that pointed out that= =20 mount honors these, since it internally uses the udev symlinks mechanism=20 to support (fs) labels, etc, so they get support for gpt-partition- labels, etc, essentially "for free". That has implications both here and for openrc, the latter of which I=20 appreciate well, as I run openrc-9999 now, having found it FAR easier to=20 isolate and report problems with new versions on my apparently rather=20 unusual system config (including fstab fs-label but not partlabel or uuid= =20 usage) directly from git, than from the MUCH too vague released-version=20 changelogs. --=20 Duncan - List replies preferred.
