[Libcdio-devel] Re: libcdio-0.83git on Solaris snv134 sees no drives

Hi,

> Thomas: when you are satisfied with a solution, post a patch here.

It will still last a few days.

Nevertheless, i seem to have my main use cases
working now. See end of this mail.

-----------------------------------------------

There is another level of consideration above
the mere technical Solaris tricks:

What about older systems which still have vold:

Shall the old /vol-addresses be used ?

Who could test whether they work with new
access mode MMC_RDWR ?

-----------------------------------------------

It is strange that the man page of growisofs
mentions /vol/.../cdrom* and /dev/rdsk/c* as
alternatives.
It would be interesting to know what the
volmgt function
  media_findname()
returns as device path of a /vol-address.

Possibly libcdio never dealt with /dev/dsk
but always with /dev/rdsk .
That would simplify our situation.

Else i would need to know which access mode
is for /dev/dsk and which for /dev/rdsk.

-----------------------------------------------

Does anybody have an idea why growisofs loads
  void *secdb = dlopen("libsecdb.so.1",RTLD_LAZY);
and inquires 
  chkauthattr("solaris.device.cdrw", ...)
rather than just trying to open the device ?
If !chkauthattr() then it errors with EACCESS. 

This looks like a workaround for a bug.
But which and where ?

-----------------------------------------------
State of sketching:

I do not yet know how to reduce SATA speed to
1.5 GBps so that my eSATA box would work
properly. So i had to replug to USB which yields
a new address for the burner.

I can list drives by /dev or by Bus,Target,Lun,
and i can burn multiple sessions to CD-RW and
DVD+RW. (Hald seems not to interfere negatively
for now. A miracle !)
