Marek Zarychta <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected]. | |pl --- Comment #8 from Marek Zarychta <[email protected]> --- IPFW is foot-shooting by design. Every single person who ever used this firewall learned that adding the entry net.inet.ip.fw.default_to_accept="1" to loader.conf is inevitable. The ABI was changed in commit 4a77657cbc011ea657ccb079fff6b58b295eccb0 (ipfw: migrate ipfw to 32-bit size rule number), and the commit message is clear in this regard. Among other things, we can read: "This changes ABI due to the changed opcodes...". If someone skipped adding this to the documentation, then the documentation has to be updated. Regarding upgrades and double reboots, this can probably be changed, or at least no longer be an official recommendation. Recommending the use of ZFS and boot environments for major version upgrades by upgrading both kernel and userland in one step in a newly created boot environment is the safest way to upgrade in 2026. If people have to use UFS, let them follow the old, official guide, but we should also allow taking some risk by upgrading in one step - sometimes it works wonkily, but usually it does work for major version upgrades too. -- You are receiving this mail because: You are the assignee for the bug.
