It should be big enough to 15 contain one full release per syspatch (~30G). 16 17- ${SRCDIR} and ${XSRCDIR} must be checked out using the OPENBSD_X_X_BASE 18 release tag. 19 20- Timezone must be set to "Canada/Mountain". 21 22Requirements for the fakeroot 23----------------------------- 24 25Before building the first syspatch, the same release used on the build machine 26must be extracted under a subdirectory of ${FAKEROOT} to allow clean comparison 27and find differing files between patched releases. 28 29e.g. 30FAKEROOT=/fakeroot 31FAKE=${FAKEROOT}/syspatch/61-000_release 32RELEASEDIR=/path/to/sets 33mkdir -p ${FAKE} 34install -m 0700 ${RELEASEDIR}/bsd{,.mp} ${FAKE} 35for set in base comp game man xbase xshare xfont xserv; do 36 tar xzphf ${RELEASEDIR}/${set}$(uname -r | tr -d '.').tgz -C ${FAKE} 37done 38mkdir -m 700 -p ${FAKE}/usr/share/relink/kernel/GENERIC{,.MP} 39tar -C ${FAKE}/usr/share/relink/kernel -xzf ${FAKE}/usr/share/relink/kernel.tgz 40rm ${FAKE}/usr/share/relink/kernel.tgz 41 42Building a syspatch 43------------------- 44 45When building a xenocara syspatch, make sure to set XSRCDIR to the directory 46where the xenocara checkout was made. 47 # export XSRCDIR=/usr/xenocara 48 49Everything is done as root under ${BSDSRCDIR}/distrib/syspatch/. 50 51Before building the first syspatch, the obj directory must be created. 52 # FAKEROOT=/fakeroot make -f Makefile.000 obj 53 54Each syspatch requires its own Makefile numbered after the patch level. 55 # cp Makefile.000 Makefile.001 56 # ${EDITOR} Makefile.001 57 -> set the ERRATA name and BUILD type 58 59The patched release can now be built. 60 # FAKEROOT=/fakeroot make -f Makefile.001 001_dummy/.plist 61 # ${EDITOR} obj/001_dummy/.plist 62 -> edit the plist to make sure it only contains files we want to end up in 63 the syspatch(8) tarball 64 65At last, a syspatch(8) can be created. 66 # FAKEROOT=/fakeroot make -f Makefile.001 syspatch 67 68Patches are incremental and must be built in order. In case an errata does not 69apply to the current architecture and to prevent a gap in the numbering, the 70"previous" fakeroot must be created manually by copying the previous one. 71e.g. 72 # cp -Rp /fakeroot/syspatch/61-010_perl /fakeroot/syspatch/61-011_sti 73
