Implementations

impl SystemChecks

pub fn new(host_executor: HostNamespaceExecutor) -> Self

pub async fn run_all(&self) -> CheckGroupResult

pub async fn has_nft_bin(&self) -> CheckResult

Checks that the nft binary, typically from the nftables package, is in PATH. Currently, the installer and protect-network rely on this.

pub async fn has_linux_util_bins(&self, bins: &[&str]) -> CheckResult

Checks that the given util-linux/coreutils/etc binaries are present in PATH. It is assumed that all of these respond to --version. On all supported systems this should be a given. Currently, the installer relies explicitly on these being present on the host.

pub async fn has_grub_mkconfig_bin(&self) -> CheckResult

Checks that either grub-mkconfig or grub2-mkconfig is present in PATH, as the installer currently requires one or the other.

pub async fn has_service_manager_bin(&self) -> CheckResult

Checks that either systemctl or rc-update is present in PATH, as the installer requires one or the other to enable services.

pub async fn has_package_manager_bin(&self) -> CheckResult

Checks that at least one supported package manager is present in PATH, as the installer requires one to install system packages.

pub async fn enough_memory(&self) -> CheckResult

Checks that total system RAM is at least 4 GB.

Manual equivalent:

awk '/MemTotal/ { if ($2 >= 4194304) print "OK"; else print "FAIL" }' /proc/meminfo

pub async fn enough_disk(&self) -> CheckResult

Checks that at least one mounted filesystem has 20 GB or more of available space.

Manual equivalent:

df -BG | awk 'NR>1 { gsub(/G/,""); if (int($4) >= 20) found=1 } END { exit !found }'
