Re: decreasing the size of the distribution

Re: decreasing the size of the distribution
Agreed on the whole - I run a router happily on a 512mb flash drive. And I didn't have to minimise a thing.

I would tend to agree. OpenBSD is a small operating system and any reasonably sized flash storage will easily contain it. Why on earth make life more difficult for yourself - as soon as you cut the OS down it becomes harder to support! I have a NetBSD system using an IDE-Compact Flash converter and simply use it as normal (at the time, OpenBSD didn't support the hardware fully). I do use flashdist on an OpenBSD firewall, with an extremely cut down subset of OpenBSD. The reason for this is not distribution size, but that the OS remains unchanged every time it boots up (flashdist uses the storage device read only) and the possibility of corruption is removed. Flashdist works well, but from experience I can say it's a bit of a pain in the arse to get working as it's always missing something. The first time I booted it up, I found it didn't include the firmware for my (wired) ethernet card by default, for instance. Save yourself the hassle and just install as normal. PK
Re: decreasing the size of the distribution
Agreed on the whole - I run a router happily on a 512mb flash drive. And I didn't have to minimise a thing. +1 I install 4.5 over the network to my router. GENERIC bsd, base45, etc45. No scripting required. http://www.openbsd.org/faq/faq4.html#FilesNeeded It fits on a 256MB compact flash with room enough to spare. If this machine wasn't on a LAN with other connected boxes I'm sure man45 and misc45 would fit as well ... I have other documentation access but would not exclude man from a stand alone box. http://marc.info/?l=openbsd-miscm=96280712907980w=2 Advantage? Whenever I have an issue I have some (some) confidence it is not anything stoopid I have done. :] # df -h Filesystem SizeUsed Avail Capacity Mounted on /dev/wd0a 240M163M 64.8M72%/ mfs:2794 7.7M1.0K7.3M 0%/tmp Unless 4.6 has grown more than it looks I expect it will also fit nicely. Best wishes.

Yes, i didn't touch your question how to find those files. Yes, i don't know why you would have to slim down, because you didn't write why you would have to do that. - Robert

If you have to ask, you shouldn't be doing it. Why would you possibly need to get smaller than the baseXX, etcXX and manXX sets? These easily fit on a few hundered MB. What modern flash disk won't fit this? Seriously, stop overthinking it. If you primary goal is to use flash (not necessarily to remove files), look at something like flashrd. -- Jason Dixon DixonGroup Consulting http://www.dixongroup.net/

Man pages are popular to remove, as are entries in /sys for other arches than your own. But I've been pestered at least four times now, by people trying to save space that shot themselves by this and broke things--and didn't know how to fix it. All of OpenBSD fits into a very small partition. Are you saying that you really don't have a flash drive (or whatever) of a gig in size? Of course I don't know what you want to do with the system once its runing, but the more complex it is, the smaller OpenBSD is going to be in comparison to that. Lastly if you do build a little shrip frankensystem, asking for help here isn't going to get a lot of sympathy. You'll be on your own. --STeve Andre'
