From: Richard Basch <probe@MIT.EDU>
The @sys convention is being changed by Transarc (the developers of AFS)
to be consistent across the various platforms. If you have used the
@sys notation and rely upon it, read on. If you do not know what I am
referring to, you are most likely not going to be affected.
The new @sys names will be of the form:
<hardware>_<os><version>
The new values will be in the Athena 7.0 release (so that we are
standard with the rest of the AFS community -- other sites will be
changing their @sys values, also).
The new @sys values for Athena's supported architectures are:
rt_aos4
vax_bsd43
pmax_ul3
I would strongly urge that everyone make the appropriate changes to any
files/directories they maintain that rely on @sys. For the most part,
this will simply entail making a symbolic link, so that both versions of
@sys will access the same data. The following are the various release
dates for the Athena 7.0 release, so that you know how much time you
have:
May 7 Friendly test.
May 23 Staff test.
June 20 Final release.
This @sys discussion has been underway for quite some time, and it is
only now that Transarc has given an official list of what they expect
people to adhere to (many sites have been requesting some
standardization of the @sys values and were involved in the final
discussion as to Transarc's recommended values).
A full list of all supported/recommended @sys values has been enclosed.
(The difference between "supported" and "recommended" is whether
Transarc supports their product on a given platform).
The following are Transarc supported values for @sys:
rt_aos4 IBM-RT/PC, AOS Release 4
rt_aix221 IBM-RT/PC, AIX 2.2.1
vax_ul3 Vax, Ultrix 3.0, 3.1
pmax_ul3 Mips, Ultrix 3.1
sun3_35 Sun3, Sun OS 3.5
sun3_40 Sun 3 (68020), Sun OS 4.0.3
sun3x_40 Sun 3 (68030), Sun OS 4.0.3
sun4_40 Sun 4, Sun OS 4.0.3
sun4c_40 Sun Sparcstation 1, Sun OS 4.0.3c
The following are Transarc recommended values for @sys:
rt_machXX IBM-RT/PC, Mach/4.3BSD version XX
rs_aix31 IBM-RS6000, AIX 3.1
vax_bsd43 VAX, BSD 4.3
vax_machXX DEC Vax nnn and/or MicroVax nnn, Mach/4.3BSD version XX
pmax_machXX DECstation 3100 (MIPS), Mach/4.3BSD version XX
sun3_machXX Sun-3/nnn, Mach/4.3BSD version XX
sun4_machXX Sun-4/nnn and/or Sparcstation nnn, Mach/4.3BSD version XX
ymp_uni50 Cray YMP, UNICOS 5.0.12
mac_mach51 Apple Macintosh, Mach 5.1
mac_auxXX Apple Macintosh, AUX version XX
mmax_machXX Encore Multimax, Mach/4.3BSD version XX
next_machXX NeXT Mach version XX
ap68k_102 Apollo 68000, SR 10.2
ap88k_102 Apollo 88000, SR 10.2
370_aixXX IBM 370, AIX version XX
370_mvs IBM 370, MVS
ps2_aixXX PS/2, AIX version XX
hp300_ux70 HP 9000/3XX, HP-UX 7.0
