I think you need sys-apps/debianutils installed too.

make install will create symlinks for vmlinuz and vmlinuz.old to the
latest and previous kernel, doing much of what you need. You need /boot
to be on a filesystem that supports symlinks and ISTR that it only
updates the symlinks if already present but doesn't create them from
scratch.

you are just wrongly assuming that they are mutually
exclusive...

seriously, one could have kernels named,
without versions, as:

vmlinuz
vmlinuz-older
vmlinuz-older2
.
.
.
vmlinuz-olderN

this way, new kernel installation, and rotation,
will be decoupled from the boot loader's configs,
effectively removing any housekeeping for the
boot loader.

There have been a relatively large number of OMR projects falling in and out 
of obscurity, forked, taken over, mixed with closed source and then die.

I was looking for an OMR package in portage to scan PDF sheets of music and 
then split different voice parts out into separate midi files - but if a 
single application will do the full workflow then I would be more than happy.

I understand there are a few apps by/for Apple, who seem to be the favourite 
OS for arty users, but I no longer have OSX running here or any applications 
for it.  There are also a number of other applications some of them for Linux 
- but I haven't found one yet in portage (TBH I wouldn't know its name off-
hand).

It is uncertain at the moment if the issue is a Gentoo one or one of

You just want a nasty recovery job if the update screws up ...

Seriously, I always just add new kernels as the new default option,
precisely so as I can go back to a working one if things go wrogn ...

Re: [gentoo-user] OCR for music (OMR)

I vaguely remember using some windows based program when archiving old music. 
The community in question had maps full of paper scores and making them 
digital would have made it much more compact and versatile. However even back 
then I remember manually writing lilypond files. I did use Linux at that time 
but wasn't aware of any OMR tools.

Eventually I stopped visiting and the project fell out of favor due to the 
immense manual labour. Literally hundreds of sheet music ranging from single 
page meant for the artists up to the combined score for the conductor.

A quick search led me to audiveris. I have no experience but it might do what 
you want. It has the option to export to MusicXML. I tried to use Rosegarden 
to read a MusicXML which "worked". It did get the notes right, but alternated 
with trebble and bass lines, being a somewhat monophonic end result.

Hope this helps

Thanks Wol, yes, I suspect asking the user to transcribe umpteen sheets of 
music notation manually from PDF won't go down nicely.

I'll check Rosegarden again in case it can perform OMR.

That's why I have Chromium, as well and LO and qtwebengine, set to use my
SSD for PORTAGE_TMPDIR on this laptop, which is limited to 8GB. MAKEOPTS
is also constricted for Chromium. As a result, the packages build more
quickly with minimal impact on using the system.

I'm not aware of any apps at all. Rosegarden is a midi editor, and might
have some scanning ability. Lilypond is a music publishing program and
can generate midi output. If you transcribed your music into either of
those programs (Rosegarden would be best) you can generate midi, but
that's work you clearly would rather avoid ...
