Author: arichardson Date: Mon Jan 27 12:02:41 2020 New Revision: 357169 URL: https://svnweb.freebsd.org/changeset/base/357169
Log: Allow bootstrapping makefs on older FreeBSD hosts and Linux/macOS In order to do so we need to install the msdosfs headers to the bootstrap sysroot and avoid includes of kernel headers that may not exist on every host (e.g. sys/lockmgr.h). This change should allow bootstrapping of makefs on FreeBSD 11+ as well as Linux and macOS. We also have to avoid using the IO_SYNC macro since that may not be available. In makefs it is only used to switch between calling bwrite() and bdwrite() which both call the same function. Therefore we can simply always call bwrite(). For our CheriBSD builds we always bootstrap makefs by setting LOCAL_XTOOL_DIRS='lib/libnetbsd usr.sbin/makefs' and use the makefs binary from the build tree to create a bootable disk image.
